Metal Etching: Dzidziso uye Practice

Chemical etching zvinoreva yamunobvisira simbi kubva ayo panyika yacho oxides kana nekubudisa residues. mumwe muitiro kwakadaro kunosanganisira kushandisa mushonga kuti chloride munyu pamusoro alkali kana iine acid mhinduro. Zvisinei kuti hasha namakemikari nevasori mhando kushandiswa, ari etching chainge chakagadzirwa nesimbi kunoda nokungwarira chaizvo kururama kwevanhu, sezvo vakadaro zvinhu kune ngozi uye neVadzidzi ganda kungaita kutsva. Kunyange zvakadaro, pamwe zvakakodzera nekugadzirira kwacho zvinokwanisika kuita kumba. Metal etching kunoita zvichiberekana chero nyaya, zvinyorwa, kudzika kana rokuyamura chishongo hunenge chero simbi pemvura. Products kuti dzinokonzerwa Ndinowana kupedzera vamwe vakasununguka nguva kuongorora ruzivo urwu.

Musimboti kwacho

Metal etching zvinogona kana zvakakwana, iyo kazhinji kushandiswa nyore yokunatsa uye haasaruri, kuti inowanzoshandiswa nokuda kushongedzwa zvinhu. Mukupera nyaya, kudzivirira nzvimbo iyo hakufaniri pasi kurapwa ichi, mumwe ainzi kukunda. Metal etching kunogona kuitwa kana mishonga kana galvanically. Muchiitiko chokutanga chigadzirwa kunobva kunyudza kupinda mhinduro. Marapirwo nguva kunobva aida etching kudzika uye mhando zvokunyama. Mushure nokubvisa simbi kushambidzwa kwazvo nemvura inotonhora, izvo dzimwe nguva akawedzera aqueous mhinduro kuti pasoda. Izvi zvinoita kuti tive nechokwadi chokuti tichingoda asidhi haangarevi Anotadzira nei.

Decorative Metal etch

Raishandiswa kuMiddle Ages nokuda kushongedzwa zvombo uye nezvombo. In runako kwavo zvigadzirwa kazhinji muduku zvisikwa unyanzvi maoko jewelers. Nokuti ichi mhando nesimbi pose pakurapa wechipiri zvakanakisisa, ndiko kuti, nzira galvanic. nzira iyi haambotauri paumbwe chepfu magasi vanhu kuti inomuka kana makemikari kurapwa, uye zvakawanda zvinobudirira nokuti inoita kuti micheto kujeka etched muenzaniso.

Galvanic etching uchidzidzira

Kuti aratidze tarenda ravo kutanga izvi kumba uye, chokutanga ndechokuti kuwana kwaibva DC voltage riri anenge kuenzana 4-7 Volt. Ideal - mhuri simba wedzerai ane chinja. Zvino zvakafanira kuti tive tireyi ane insulating zvinhu, izvo zvichava electrolyte. Sezvo yokupedzisira inogona kushandiswa iri zvine mhinduro tsika munyu, asi kazhinji kushandiswa chinangwa yakanyauka ichi sulphate. Iron rinoshandiswa dare uye simbi, uye mhangura - nokuti ndarira, nendarira uye mhangura. The simbi amboita zvinoda degreased kare. Nokuti chinangwa ichi kwakanyorwa soldered mhangura waya vakabata nayo akanyika kwemaminitsi 5 kuva mhinduro kubva yavaibvisa hydroxide, preheated kuti tembiricha 50 ° C. Zvadaro, preform iri zvaitambidzwa maminitsi mashoma imvura ine zviri 15% sulfuric acid, uye ipapo kushambidzwa kwazvo nemvura inopisa. Last regadziriro Danho - kugadzirwa yemastic. Netini bhokisi kunovhengana namo, rosin uye namo munyika inorwara 4: 2: 3 uye zvinonyauka kuwana homogeneous guru. Kana haachandidi, kuchiisa icho nenzira nhete jira uye yakasimba nemotokari ne zvishoma nenharo workpiece chero bedzi akafuka yunifomu mutete rukoko. Shure kwaizvozvo zvose mukukutu, kushandisa mvura ruvara kupenda zvinodiwa muenzaniso uye vadzime putty nebanga apo tinofanira kuwana zvakadzama. Zvino muriise ari electrolyte kubudikidza plugging mu chinouraya kune zvakanaka padanda uye kuti waya pamwe kubvisa chiratidzo misa chero simbi chinhu uyewo kudzikisa akaibayirira electrolyte. Pamusoro kuvakwa etching Unsolder waya sukurudza akawana turpentine Paaidzidzisa uye kuita wokupedzisira pakuvakwa (kukuya uye makorari).
